A USAID-funded expedition with The Mountain Institute head into the shadow of Everest to work with local Sherpa on climate change adaptation and do groundbreaking (and hair raising) research paddling a thin-skinned raft through razor-sharp glacial ice on Lake Imja, to determine how dangerous the lake is and its chances of causing a mega flood over the entire Everest trekking route. Music by Gingerr Shankar and Harry Aspinwall.
